This lecture examines the large number system in humans and animals, highlighting Weber's Law as a driving principle. The discussion covers experimental evidence for this law in number discrimination and estimation, and proposes that it arises from the brain's limited precision when representing a wide range of quantities. Furthermore, the lecture explores individual differences in large number processing, demonstrating a correlation between Weber ratios and mathematical performance.

This lecture explores specialized cognitive mechanisms for number processing, distinguishing between a small number system for quantities up to three or four, which allows for immediate and precise recognition without counting, and a large number system for greater quantities, characterized by approximate representations governed by Weber's Law, where discriminability depends on the relative difference between quantities.

This lecture explores mechanisms underlying word learning, focusing on further learning constraints. It highlights the taxonomic constraint, where learners assume new words refer to categories, often at the basic level. However, verbal cues also allow them to consider more abstract categories. We further examine the challenges of verb learning, arguing that grammatical context is a crucial source of information, enabling learners to infer the meaning of verbs based on their syntactic context.

This lecture explores the evolutionary basis of cognition, suggesting that cognitive mechanisms are often specialized for specific purposes, much like physical adaptations in animals. It then focuses on the challenge of word learning in humans, highlighting the inherent ambiguity and how general associative learning, such as cross-situational learning, provides only a partial solution. The discussion introduces the concept of word learning constraints, including fast mapping, mutual exclusivity, and the whole object constraint, which act as innate biases to narrow down potential word meanings.

The lecture introduces cognitive psychology by examining human abilities within the broader animal kingdom. It begins by questioning whether humans are special among animals, touching upon intelligence, tool use, reasoning, and language. The discussion highlights both unique human traits, such as advanced mathematics, and shared ancestral traits, like the serial position effect and basic learning/forgetting curves. These shared memory mechanisms, though ancient, are shown to influence complex human behaviors like language processing and decision-making. The lecture further explores the concepts of ancestral and derived traits, including convergent evolution exemplified by vocal learning in disparate species, contrasting it with common descent explained through the serial position effect across primates.

This lecture explores the developmental stage of adolescence, examining the concept of "storm and stress" and its manifestations, such as conflicts with parents, mood fluctuations, and risk-taking behaviors. It investigates the role of social factors, particularly peer influence and rejection, on adolescent choices and risk engagement. The discussion also covers identity formation, outlining different statuses and the importance of exploration. Finally, it touches upon moral development, contrasting adolescent reasoning with that of children and adults.

This lecture explores the cognitive changes occurring during adolescence, contrasting them with childhood and adulthood. It highlights improvements in memory, noting the development of more strategic approaches like elaboration, clustering, and rehearsal. The discussion then shifts to attention, explaining the enhanced abilities in focused and divided attention during this period. Furthermore, the lecture examines the development of executive functions, including inhibition, flexibility, and planning, linking these to brain maturation. Finally, it touches upon changes in thinking and intelligence, referencing Piaget's formal operational stage and differentiating between fluid and crystallized intelligence and their developmental trajectories.
